Manohla Dargis confirms my earlier post that Spider-Man 3 really has more peaks and valleys than the two previous movies. But I think it's mostly valleys.
I like the part where Tobey Maguire is told "to stop relying on those great big peepers of his: simply widening your eyes to attract attention does not cut it when you’re over 30." Boyishness has its appeal, and Tobey's friend Leonardo diCaprio was still doing the naughty boy act when he did Catch Me If You Can. But then he also made Gangs of New York and now he's all beefy and, uhm, manly.
Anyway, read Dargis' review here.
